    "How far can such a small device transmit? Lao Peng, could it be the distance from the front yard to the backyard?!" Mao Geng stroked the two treasures, and of course he didn't hope that what he said was true.  Yes, but after all, I was full of doubts in my heart, so I was joking but also worried.

    ¡°The first successful test was from the front yard to the backyard. However, longer distance tests have also been done. The 10-kilometer transmission test was pretty good. I plan to do further transmission tests on Sakhalin Island again.  Haha, in Lin'an, I did all my experiments secretly."

    "Lao Peng, no matter how much you engage in underground research, you must have someone to cooperate with you in sending and receiving experiments. Haha, Lao Peng, who cooperated with you? I heard that you have a house of concubines, why didn't you see her?  Come to Sakhalin Island!" Mao Geng noticed that there were two girls who looked like maids on the boat with Lao Peng. One of them was quite pretty. When asked about it at the time, Peng Qinfang only said that she was a maid.

    "Oh, it depends on what you said! Wen Yuan gave me a girl, but it's a pity that the child is too young. Hey, he is still a fifteen-year-old loli, too young, too young! Oh, don't talk about this, I  I asked the maid to help. I just told her to press the button regularly, and I didn¡¯t tell her what it was. Of course, to be on the safe side, I brought her here this time, and she is on the boat at the moment. Hehe! This  To ensure that the secret will not be leaked." This time to Sakhalin Island, Peng Qinfang originally planned to take only this maid. This was for the sake of confidentiality. He did not expect to take the "concubine" there, but Wen Yuan did not care.  Seven twenty-one, I just brought her with me, just bring her with me, Lao Peng thought to himself, in fact, I have no interest in lolita.

    Mao Geng knew that Lao Peng was more conservative, so he put away his gossip and returned to the topic:

    "Lao Peng, do you think a transmission distance of 50 kilometers can be successful?" Mao Geng thought to himself, if there is a transmission distance of 50 kilometers, it can basically be put into practical use. If the distance is far, a relay method may be used.

    Peng Qinfang thought to himself, "Aren't you looking down on me?" Although Peng Qinfang kept a low profile, he was also quite arrogant. He instinctively raised his voice:

    "Chief Mao, you don't know much about the history of radio. It's like this. In 1904, the Russians' spark transmitter and ore detector receiving device had a transmission distance of almost a thousand kilometers. The Russians' technology is no different than yours.  The technology in front of us can be said to be at the same level. In the same year, 1904, the world's first electron tube was born, invented by Fleming. However, let me tell you, although his electronic diode was  It worked very well in the laboratory, but it was very unsuccessful in actual use as a geophone. It was not as good as an ore geophone! In the Russo-Japanese War in 1904, both fleets were equipped with spark transmitters and ore geophones.  Receiver device. Technically, the theory I studied was from the late 20th century. It should be better than the Russians and Japanese in 1904. Not to mention the transmission distance of one thousand kilometers, there should be no transmission distance of three to five hundred kilometers.  question."

    "Oh, Lao Peng, don't get me wrong! Don't I understand this? I thought that radio had to wait until the electronic tube came out to achieve long-distance transmission! I am ignorant and ignorant!"

    "The earliest radio detector was a powder detector, also called a condensation detector. Marconi's transoceanic wireless telegraph in 1901 shocked the world. It spanned 3,500 kilometers across the Atlantic Ocean and the wireless telegraph was successfully received. The detector he used was this  The original powder detector. It was only later that someone invented the ore detector. The ore detector technology was already an upgraded version. The ore detector technology in 1904 was probably not very mature, and galena was probably not used yet.  , red zinc and other advanced materials, after the ore detector matured, it was used until the 1920s. After the ore detector came the electron tube detector. There are tube transistors, which are of course different. They have high sensitivity and do not require much power.  Realize long-distance transmission and reception of radio signals. Once an electric spark transmitter is discharged, it can produce an instantaneous power of hundreds of watts or kilowatts. Later, the tube and transistor radio transmitters, and the general transmitter are 5 watts.  , 15 watts, this is really incomparable.¡±

    Everyone has a side that likes to be a teacher, and Peng Qinfang is no exception.  Now that Lao Peng has entered the role, in Lao Peng's eyes, the look in Mao Geng's eyes feels like a primary school student's hunger, so Lao Peng has the urge to be a teacher and continues to popularize science:

    "In the 1940s, our party's radio station in Hong Kong only had a power of 5 watts, and it was still a piece of equipment. Some measures were taken, such as raising the antenna, and telegraph communication with Yan'an, 1,700 kilometers away, was still going on!  Of course, not to mention wireless communication technology in the 21st century.¡±

    Mao Geng smiled, feeling a little silly.  I really know nothing about the history of radio.  It turns out that radio is not a high-tech thing, and can be played with very simple methods.

    "It's too far, too far"??Don't worry, Chief Mao, the radio will still work without the tube.  I'll tinker with it a little more, and with a transmission distance of three to five hundred kilometers, it shouldn't be a big problem.  "

    "That's good! I knew that Lao Peng was a man of action. He solved a big problem for us quietly." Mao Geng immediately thought that after Lao Peng made such a great contribution, he should be rewarded. Look.  It seems that Lao Peng doesn't like underdeveloped lolita. It seems that Cai Jianwen needs to help find a girl, right!  It will be done immediately after Cai Jianwen and Wen Yuan's trip to Korea is over.

    Next, Mao Geng wanted to see a radio demonstration, but the battery Lao Peng brought was out of power, so he had to give up.  Thinking about it again, even if the test on the ship is successful, it is only the distance between the bow and the stern, which does not reflect the performance at all.  Since in real history, Marconi was able to achieve long-distance wireless communication of more than 3,000 kilometers with backward technology, Lao Peng's technology is an upgraded version, and he can handle wireless communication of 300 to 500 kilometers. It is expected that he should be able to do it with ease.

    But it was said that Wen Yuan, Cai Jianwen and his party had arrived in Goryeo at this time.  Wen Yuan, Cai Jianwen and their entourage set off with the Koryo mission, and within a day they arrived at the royal city of Koryo to open the capital.

    As mentioned earlier, the Sado Special Zone Ceremony also invited envoys from Korea. The envoy from Korea was called Li Zhichun. Li Zhichun himself was a military general and was known to be both civil and military. Of course, the most important thing was that he had a powerful father.  His father is Li Yimin. Li Yimin is currently serving as the Minister of Pingzhang Affairs of Goryeo Tongzhongshu. He can be regarded as the prime minister and privy envoy of Mingzong of Goryeo. Now it is the time when Goryeo military generals have exclusive power. Since 1170, military generals began to have exclusive power.  , the government of Goryeo basically had no civil servants, and even the King of Goryeo became a puppet.  Therefore, Li Yimin basically has the final say in the current affairs of the Goryeo Dynasty.

    Originally, Li Yimin had great power and lived a very comfortable life. However, since last year, pirates have been committing crimes along the coast of Goryeo. In addition to robbing property, they also kidnapped a lot of people. Many ships were also robbed by pirates, which temporarily caused confusion between the government and the public in Goryeo.  There were complaints.

    Later, it was reported that the prince of Liao Kingdom gathered a group of brutal pirates to commit the crime. Fortunately, the main target was not Goryeo but Japan.  Of course, those evil pirates had no sense of strategy at all and actually engaged in indiscriminate robbery. Even the Song and Jin empires were poisoned by them.  Later, the Song Dynasty sent a large number of warships to Japan, claiming to have wiped out the Khitan pirates.

    However, pirate robberies still occur from time to time along the coast of Goryeo. Although they are not as frequent as before, they are still as fierce as ever, and Goryeo's warships cannot stop them at all.  For this reason, when Japan invited Goryeo to send envoys to attend the Sado Special Zone Ceremony, Li Yimin immediately decided to send people there. It was inconvenient for Goryeo to have official relations with the Song Dynasty, but there was no taboo with Japan, so he took this opportunity to learn about pirates.  situation, by the way, I would like to test whether we can set up an international anti-piracy alliance or something.

    After I went there, there was indeed a response, no!  A businessman Cai Jianwen came. It is said that this person has a background in the Song Dynasty. Needless to say, it should be the Song Dynasty who is playing businessman diplomacy.  As for the great novelist Moon Won, it goes without saying that he probably came to Goryeo to build his international reputation. What¡¯s abominable is that a bunch of Goryeo writers went crazy over it. It¡¯s really unreasonable. Although I, Mr. Li, also like this Moon Won.  Novel, but the novel is just a trail, just watch it for a while, as for being obsessed with it!

    Li Zhichun has just told what he learned this time. He didn¡¯t expect that among the pirates that the Khitan princes gathered, there were actually descendants of the former Tamluo. According to the people of Song Dynasty, it should be this group that robbed Goryeo.

    This story is of course made up by Wen Yuan. As a qualified novelist, making up stories is the basic quality. Wen Yuan¡¯s stories are compiled with great care.  In this version of the story, a descendant of the Fu family of King Tamluo Zijian was determined to restore the country, so he formed a pirate team with the descendants of the Khitan Yelu family. However, the pirate group of the descendants of the Fu family was smaller in scale, and they still had to listen to Yelu.  Your Majesty, so most of the time you have to follow the big pirate team to mainly cause harm to Japan, and only visit Goryeo when you have free time.

    Later, this group of pirates from the Fu family heard that the Song Dynasty was going to punish King Yelu. Fu, who was well versed in the art of steering the ship according to the wind, immediately parted ways with King Yelu. King Yelu was subsequently wiped out, but the Fumen pirates were basically unscathed.  .

    Wen Yuan also revealed some gossip. For example, it is said that the person named Fu has a relationship with Han Guanzhou, a figure in the Song Dynasty, and may even have access to the court. Therefore, the Song Dynasty may not take action against them, and Fu  Someone was very active, and it is said that officials of the Song Dynasty who sympathized with Tamluo's plight had already expressed their opinion that the Fu family should be helped to restore the country.

    This story is quite round, at least when Li Yimin heard it, he sighed in his heart: No wonder he wants to harm Goryeo!  It goes without saying that the Tamrafu family's hatred for Goryeo is worth it, damn!  But Da Song, how could you let it go??Supporting such terrorists!  It's so unprincipled.

    It seems that we cannot count on international support. In today's world, the Jin Empire is naturally second to none on land, but the Jin Kingdom and the Song Dynasty are not close to each other in maritime strength. The pirates of King Yelu of Khitan can easily overwhelm the navy of the Jin Kingdom, and the Song Dynasty can  King Yelu was completely defeated, so the Jin people could not provide any help at all in the matter of pirates.  It seems you still have to rely on yourself.

    "Rong'er, your father asked you to imitate meteor bombs. Have you made any progress recently?" Li Yimin asked his other son Li Zhirong. Li Yimin felt that as long as he could make meteor bombs, he would be stunned by this new weapon.  , and you can also kill the pirates with dignity.

    "So that my father will know that we hired Jin craftsmen with a lot of money some time ago, and we have made quite a lot of progress. We expect that the meteor bomb will be made soon." In fact, Li Zhirong was a bit bragging. Even though he hired Jin craftsmen, the things he built were still not good enough.  How it works, he doesn't know. Just in terms of gunpowder formula, the gap is obvious. Although the craftsmen of the Jin Kingdom inherited the gunpowder technology of the Northern Song Dynasty, the gunpowder technology of the Northern Song Dynasty is actually far from reaching the best of Mao's technology.  Of course, the ratio is impossible to achieve
